Letters Patent No. 96,507, dated November 2, 1869.

nllnuwvmay WINDOW.

The Schedule referred to in these Letters Patent and making part cf the same.

To all whom it 'may concern Be it known that I, LEVI TILL, of Sandusky, in the county ot' Erie, and State of Ohio, hare invented a new and useful Imprzwelnentin Windows; and I do hereby declare that the'lbllowing is a full', clear, and exact description thereof, which will enable others skilled in the art t0 nlakeand use the same, reference being had to the accompanying drawings, forming part ot' this specification.

Y `l\l y invention relates to windows; and consists in an improved construction and armngement otpznts, whereby they may he more conveniently cleaned and repaired.

Figure 1 represents a front elevation of' a window constructed according,r to my improvement, with apart broken away at the top;

Figure 2 represents a-horizontal section of the saine, taken on the line x :c ofiig. 1 and Figure 3 is a transverse sectional elevation.

Similar letters otl reference indicate corresponding parts. l

I make the stiles of' the sash in two parts, a b and c d, and fit the lpa-rtsl b and d to work up and down between the stops e fg, and preferably in grooves therein.

At one side I hinge the parts ac to the other parts, as represented at h, and at the other, side I connect the two parts byspringstops 'i or other suitable fastenings.

In order to cause the upper sash to open freely past the central stop' f, I make it slightly narrower than the lower sash, and to cover the joints of the two parts of the Stiles, and form shoulders for the sash to close against, I arrange the outer and central stops to lap the said joints, as clearly shown in the sectional tie. 2.

Drlhe sash-weights may be connected to the parts l:

4d of the stiles, and when it is desired to swing the Asash open, .they are first raised to the top, and discon-` nected l'roln the parts b d, to which they are connected by the spring-stops, in order to prevent the weights on that side I'rom suddenly falling. They may be the swung open, alter being drawn down again.

for 'both sashes will be made the ysame width, and the sash will also be equal in width.

Haring thus described uy invention, v

I claim as new, and desire 'to secure by 'Letters Patent- 4 The combination of the pocket. a with sashes hung upon slides, in the manuel' and for the purpose specified.
